org.hibernate.MappingException: Unsupported cascade style:

lgas · **Joined:** Fri May 06, 2005 2:31 am **Posts:** 1

I am getting an exception saying that "create" is not a supported cascade style... yet the Hibernate 3.0 documentation suggests that it is, and that in fact it is how I would acheive what I am trying to do.... specifically create two persistent objects, one which contains the other in a collection, save() the parent object, and have the child object in the collection created/saved as well.

Is "create" no longer a valid cascade style? If so, a) what is the alternative, and b) I'd suggest you update the docs. If it is a supported style, then what am I doing wrong to get this exception?

Thanks,

I believe that create is not allowed as a cascade attribute value on <set> elements.

If you look at the documentation at chapter 6.2: http://www.hibernate.org/hib_docs/v3/re ... ns-mapping

At line 6:

Code:

<map
    name="propertyName"                                         (1)
    table="table_name"                                          (2)
    schema="schema_name"                                        (3)
    lazy="true|false"                                           (4)
    inverse="true|false"                                        (5)
   cascade="all|none|save-update|delete|all-delete-orphan"     (6)
    sort="unsorted|natural|comparatorClass"                     (7)
    order-by="column_name asc|desc"                             (8)

forget about 'create', this is 'persist'
